Porous carbon materials are widely used as electrode materials for supercapacitors due to their large surface area, high conductivity, tunable pore size, and low price. In addition, the N-doping of carbon materials is an effective way to further enhance the electrochemical performance of supercapacitors. In this study, N-doped porous carbon textiles (N-PCTs) were prepared from waste cotton textiles (WCTs) as electrode materials for supercapacitors. WCTs were stabilized in air and then carbonized under inert atmosphere. The prepared porous carbon textiles (PCTs) were doped by nitrogen using urea. The final N-PCTs were characterized in terms of their pore properties, morphology, and electrochemical performance. The N-PCTs exhibited a specific capacitance of ~230 F/g and an excellent cycling performance of ~100% at 5 A/g after 1,000 cycles. |
